Seacock Assembly

I often get asked for a video on how I use InspectX while in the field, so today I created a short video of just one finding while in the aft lazarette bilge. In this video I focus on just the live bait-well manifold assembly and some issues on how it was constructed.

Clearly there are a number of other findings that can be seen in this video but I chose just one so you can get an idea of a typical entry. I like to consolidate my findings together as much as possible, which is why I placed these two separate issues under the same finding in the report. 

Here's an example of a 'Quick Insert Option' phrases that I modified slightly to fit this finding in this case. I have these saved under 'Seacocks/Sea-Valves' - feel free to copy/paste this phrase into your version of InspectX and adjust to your liking. 

The aft lazarette live bait-well pump's raw water inlet manifold was not constructed in accordance with ABYC Standards (the through-hull fitting was not directly connected to a seacock valve).   Install a seacock valve directly to the through-hull fitting (ABYC Standards H- through-hull fittings and seacocks shall be connected directly). Exception: If space constraints prevent meeting H- then one non-flexible component may be installed.


The aft lazarette bilge raw water inlet manifold's piping assembly did not appear sturdy enough to meet the minimum ABYC recommended standards for static load. Also, some porosity corrosion was developing on some of the aft lazarette bilge seacock discharge valves. Refit the seacock assembly, as necessary (ABYC Standards H-27.7.1: A seacock shall be securely mounted so that the assembly will withstand a 500 pound (227 Kg) static force applied for 30 seconds to the inboard end of its connection fitting, at any point in its most vulnerable direction, without the assembly failing to perform as intended). Investigate further, clean the corrosion and monitor or replace as necessary.
